Superior CPU Cooling for Peak Performance
The Thermalright Assassin King 120 SE CPU Air Cooler is engineered for efficient heat dissipation, featuring 5x6mm heatpipes with AGHP III technology. This design combats inverse gravity effects, ensuring optimal performance whether your PC is oriented vertically or horizontally. With a 235W TDP rating and a quiet TL-C12C PWM fan (≤25.6dB(A)), it provides powerful cooling without excessive noise, making it suitable for gaming and demanding workloads. All necessary mounting hardware for Intel and AMD platforms, along with TF4 thermal paste, are included for straightforward installation.
The TL-C12C PWM fan operates at 1550rpm±10% with an airflow of 66.17 CFM, balancing effective cooling with a low noise level. Its S-FDB bearing ensures a long industrial service life of up to 20,000 hours. The cooler's dimensions are 120(L)x73(W)x148(H)mm, with a height of 148mm making it suitable for most medium-sized computer cases. This air cooler is compatible with a wide range of Intel sockets (LGA 1150/1151/1200/1700/1851) and AMD AM4, providing broad system support.
For Indian builders, this cooler offers a reliable cooling solution that can handle the heat generated by modern processors, especially during extended gaming sessions or intensive tasks common in India's warmer climate. Unlike some local alternatives, it comes factory-sealed with all components for a complete installation. All customs duties and GST are pre-paid, with delivery via ExpressBox tracked shipping within 12-14 days.
Superior Heat Dissipation for Demanding CPUs
The Thermalright Assassin King 120 SE utilizes five 6mm heatpipes with AGHP III technology, designed to counteract gravity effects and ensure efficient heat transfer from your CPU. This advanced design allows it to handle thermal loads up to 235W TDP, providing superior cooling compared to basic air coolers or stock solutions. The TL-C12C PWM fan operates quietly at ≤25.6dB(A) while delivering 66.17 CFM of airflow, ensuring your system remains cool and stable during intense gaming or heavy multitasking, even in warmer Indian ambient temperatures.
Ideal for Gamers & Power Users; Skip if Building Ultra-Compact
This cooler is perfect for gamers, content creators, and users running demanding applications who need reliable CPU cooling without excessive noise. Its 148mm height fits most standard ATX and Micro-ATX cases. Skip this cooler if you are building an ultra-compact Mini-ITX system where clearance is extremely limited, as its dimensions might not fit. For users with extremely high-end CPUs requiring liquid cooling, this air cooler may not offer sufficient thermal headroom for extreme overclocking.
